        \textit{Effects of number and difficulty of response options.} Cell entries are OLS estimates and standard errors. The outcomes are answers to the questions: correct~=~1, incorrect~=~0. The listed predictors are also coded 0 or~1. All regressions include fixed effects for each question. The baseline condition for column (1) is ``three response options''; for column~(2), ``easy response options''; and for columns (3) and~(4), ``open-ended questions.'' Standard errors are clustered at the respondent level.
